i searched for info on this but couldn't find anything, this weekend I have a church gig outside with only vocal monitoring so my usual straight to pa method won't work, the amp being provided is a really nice 50 watt Marshall clone with no fx loop so no 4cm. I setup a preset according to the manual using an fx loop block and output 2 but am not for sure how to set my levels and output. I'll be using fx only thanks
